Young's modulus
Y = (F/A)/(ΔL/L)
Where: A = area (m²) / amplitude, ΔL = ΔL, F = force (N), L = length (m) / angular momentum / inductance, Y = Young's modulus
Solved example
Given: A = 7, Delta_L = 5, F = 10, L = 4
Find: Y (Young's modulus)
- Formula: Y = F·L/(A·ΔL)
- Substitute the values: Y = 10·4/(5·7)
- Result: Y = 1.142857 Pa
Answer: Y = 1.142857 Pa
